Wild Dog live in packs that are usually dominated by an Alpha breeding pair. The female has a litter of 2 to 20 pups, which are cared for by the entire pack. These dogs are very social, and packs have been known to share food and to assist weak or ill members. Social interactions are common, and the dogs communicate by touch, actions, and vocalizations. African wild dogs hunt in formidable, cooperative packs of 6 to 20 (or more) animals. Larger packs were more common before the dogs became endangered. Packs hunt antelopes and will also tackle much larger prey, such as wildebeests, particularly if their quarry is ill or injured. African hunting dogs are endangered. They are faced with shrinking room to roam in their African home. They are also quite susceptible to diseases spread by domestic animals.Most predators rely on stealth to hunt their prey, but wild dogs rarely require such tactics. The dogs are built for high stamina chases. A typical hunt will involve the pack spreading out in a line to cover more ground and give each member space to manoeuvre. Upon finding prey the dogs will immediately approach and test the animals’ defences, probing a herd for any weak members. Once a target is selected, the pack attempts to panic and separate the herd. The pack then gives chase to the selected individual, with some dogs performing flanking movements to cut off any avenues of escape. Like an Olympic cycling team, the dog at the head of the chase will pull back as they tire and another one will take their place. Eventually, after a few kilometres, the prey begins to become exhausted. At this point the pack, with their high endurance and teamwork, easily take the animal down.
